A bandwidth control scheme for connectionless ATM traffic with multiple traffic classes

A bandwidth control mechanism is proposed for ATM networks that can control of bandwidth usage in the presence of both connection-oriented and connectionless traffic, as well as multiple classes of connectionless traffic. The bandwidth control mechanism (for managing connectionless traffic) operates at three levels. At the topmost level, bandwidth is dynamically regulated between connection-oriented and connectionless traffic based on the utilization of each traffic type. At the next level, bandwidth is controlled between different classes of connectionless traffic, such as real-time traffic, bulk data traffic, and so on. At the lowest level, bandwidth is distributed among flows belonging to the same connectionless traffic class.
